The book («Два шрифта одной революции») is dedicated to a very vivid but still unexplored chapter in the history of Russian typographic tradition. At the center of the authors’ attention are two typographic symbols from the 1920s and early 1930s: Sergey Chekhonin’s lettering and the rectangular type of the Constructivists. The book is divided into two sections: ‘Primitive Type’ and ‘Chekhonin’s Type.’ The main concept of the publication lies in the collision of aesthetically incompatible styles that were nevertheless brought together by the Russian Revolution.
